This prototype Rocky Mountain Prototype Sherpa adventure bike sort of invented itself while the team were researching Rocky’s new Blizzard fat bike. Like the Blizzard, the Sherpa is an old Rocky Mountain bike name that’s been re invented. In this case, as a ’27in+’ adventure bike. It’s what Andreas Hestler described as an ‘overlander bike’ or a fat-biker’s summer wheels.

Is that a Burmese Snow Tiger? Or a Nepalese Snow Dragon. Help!

The Sherpa is based on a 95mm travel Rocky Mountain Element frame, with a regular 142mm wheel spacing, so it can run a triple if needed. Rocky is keen to point out that it’s a concept bike at the moment, but it was causing a big stir on its stand. The bike also features a dynamo hub and inbuilt USB charging port for your GPS and Instagrammatron machine, so you can document your wilderness adventure (as long as you only adventure in 3G service…). The Sherpa, fact fans, was Rocky Mountain’s first named bike back in the ’80s.

Carbon front end and a one-by. That’s soooo enduro, er, dude.

A regular back end means you can still run ‘normal’ 27in wheels in there.
